Soon to be mother in law

Hello everyone. I wanted to vent a little since I don't have anyone else to vent to really. Lately my fiancé's mother had been really getting on my nerves. Our car broke down so we have been asking her for rides every now and then which really sucks! I mean it is nice sometimes but i would rather just be my boo and I when we are going on a date. I appreciate all the help and all that but her advice sometimes pisses me off. I didn't use to mind but lately I have just been getting more livid with her. She was telling us to lie to our landlord about our cats so we wouldn't have to pay. And when my fiancé and I have an argument, she goes and tells her mom. Which is perfectly fine until she comes back and tells me her mom told her that we should go to couples counseling since we got into an argument about something small. I don't remember the argument but it wasnt anything big and bad. I think it was about how she was always playing games 24/7 and ignoring me when i tried talking to her. So naturally i got mad at my soon to be mother in law for jumping to the situation. It always feels like when my fiancé goes to vent to her mom, her mom always has advice that leaps to an assumption! But when i am with them she just tells us that we are annoying when we play fight. I love her but I don't know how long I can keep up this sweet daughter in law act....advice?
